cxl/core: Format the memdev serial number as unsigned in TP_printk

Browse Source 
The CXL memdev serial number is a u64 PCIe Device Serial Number, but
the tracepoints format it with %lld. Devices whose vendor OUI sets
bit 63 therefore appear with negative serial numbers in formatted
trace output.

Note that the trace data itself is already stored correctly as u64.

Format the TP_printk serial as unsigned decimal, %llu, to match the
underlying value.
